In order to achieve this purpose, we set up a study model and analysis the investigated data. and The results of analysis is that success factors affecting both a finance and the other part are price, customer service and market efficiency. Success factors affecting to a finance are price, customer service and quality assurance and Success factors affecting to the other part are price, customer service and market efficiency. This study will be used to establish strategy of distribution of resources appropriately for EC companies.

Thermodynamic performance of eight zeotropic R-22 alternative refrigerant mixtures selected by AREP(R-22 Alternative Refrigerants Evaluation Program) and R-32/R-125/R-134a(23%/25%/52%), namely R-407C were evaluated by the "drop-in" simulation method. An existing air conditioner was selected and its design data were used for the simulation. "ARI Test A" air conditions were applied. The degree of vapor superheat at the compressor inlet fixed at $5^{\circ}C$ for all the mixtures. The results of the simulation were compared with those of R-22. COPs of all mixtures except for R-32/R-227ea(35%/65%) and R-32/R-125/R-134a(10%/70%/20%), were higher than that of R-22 by 2%~8%, while the capacities were all lower than that of R-22 by 13%~27%. COP of R-32/R-134a(40%/60%) was 2.4% higher but the capacity was 15% lower than those of R-22. In the case of R-32/R-134a(30%/70%), COP and capacity were 5.5% higher and 15% lower than those of R-22, respectively. Among the ternary mixtures, R-407C and R-32/R-125/R-134a(30%/10%/60%) showed the best performance. COP of R-407C was 2.4% higher than those of R-22 but the capacity was 15% lower.

The Internet has produced a great variety of VOC data. However, they are hardly helpful for CRM because they are not integrated with VOC data of the related businesses yet. This paper has set up a system for the said VOC data to actually become helpful for CRM. The system has two aspects. From the aspect of products, the customers' needs for products will be analyzed to produce what they actually want. From the aspect of customers, on the other hand, decent relationships with them shall be maintained constantly by thoroughly analyzing all the related data. The analyses on both of these aspects have the advantage of maximizing customer satisfaction by active CRM that makes us recognize what customers prefer, or complain of in advance and then provide them with tailor-made service.

Sulforaphane is a sulfur-containing substance found in large amounts in cruciferous plants and has been reported in several studies to have anticancer effects. Kale is a representative cruciferous plant known as a superfood and is widely used as an ingredient in various dishes. In this study, in order to investigate a cultivation method for increasing kale’s content of sulforaphane, kale was treated with geraniol or methyl jasmonate and water stressed during cultivation using a aeroponic culture system in a fully enclosed plant factory. Geraniol or methyl jasmonate were sprayed on the kale’s leaf surface once a day for 2 days, and water deprivation stress was conducted for 3 days after 7 days from first treatment day. No difference in growth between control, geraniol, methyl jasmonate treated groups were observed during cultivation. The study results showed that the kale sulforaphane content increased by 60% in the group treated with geraniol compared to the control group and that the group treated with water deprivation stress in addition to geraniol showed a significant increase of 414%. These results show that kale with an increased content of sulforaphane can be grown and that geraniol can be a good research material for increasing the content of functional substances in plants.

The scientific evaluation on enterprise helps establishing better management policy. Financial index has been used for the enterprise evaluation as the objective data. However, the necessity of the subjective data for competitive power evaluation is advocated recently. Therefore, in this paper, we propose an evaluation model of competitive power on enterprise by fuzzy integral, using the objective and the subjective data. The evaluation factors are composed to the financial index, top management, product, organization and enterprise's environment. These factors are grouped by detailed sub-factors of 16 units. Lastly, utilizing these factors, the efficiency of this method was shown by the result of the case study of 10 manufacturing enterprises.
전자상거래 효율화를 위한 Web Mining기반 수요예측방법

본 연구에서는 효율적인 천자상거래를 위해 Web Mining을 기반으로 고객의 수요를 예측하고 고객요구에 대응한 능동적인 생산을 위해 생산자의 구매수요를 공급자의 입장에서 예측하는 방법을 제안하였다. 먼저, 고객의 구매정보를 분석하여 다양한 고객의 구매패턴을 찾아내고 이를 통해 고객의 수요를 예측하였다. 이렇게 예측된 수요는 생산업체에 모여져 생산전략을 수립하게 된다. 생산전략이 수립되면 생산업체는 부품의 수급을 위해 공급업체에 대한 부품 구매일정과 고객의 장기 구매패턴을 고려한 생산일정을 수립하게 된다. 이렇게 수립된 구매일정과 생산일정에 의해 공급자에 대한 주문과 생산이 이루어지는데 이때 공급자의 입장에서 구매자의 요구에 능동적으로 대응하기 위해서는 구매자에 대한 이해가 필요하며 이를 이해 공급자가 자신이 공급하는 구매업체들의 거래정보를 분석하게 된다. 본 연구에는 이와 같이 고객과 생산업체, 구매업체와 공급업체를 하나로 연결하여 분석하였다.
